Today my forum logo disappeared from the iOS app. It’s exactly the same as in Mobile: Site logo disappeared in iOS mobile app and I suspect that the same solution will work - ie removing and adding the forum. But I wonder what caused it. Could it be related to rebuilding the app earlier today (see "…

If your site has working HTTPS, you can also enable “force https” in your site settings. This resolved many issues with my site images/logos, but these were also mixed content warnings in Chrome. Might help.

Potential solution from the topic you linked: [图片] Mobile: Site logo disappeared in iOS mobile app I noticed this while working on the iOS app this week. If you remove and re-add the site, the image will show up again. You’ll have to sign in again, of course.

I’d spotted that :slight_smile: [图片] Jonathan5: I suspect that the same solution will work - ie removing and adding the forum Unfortunately I’ve just tried it and it didn’t work.

The logo in the app is pulled from the apple_touch_icon_url entry in your site’s /site/basic-info.json endpoint. Can you check whether that URL is correctly returning a logo? If not, you need to fix that in your instance, and then quit/restart the app.

I set force https, then removed and added the app, but it made no difference to apple_touch_icon_url in /site/basic-info.json and no difference to the iOS app. Tonight I’ll try rebuilding the app. I wonder what went wrong, as it was all working for nearly a year until today. Today was the first tim…

I think it turns it on automatically if you have an email set in the LETSENCRYPT_EMAIL field of your app.yml. I did not but I had a wildcard SSL from the domain, so I used that instead.

On ssllabs.com it shows the certificate as valid from this morning, a couple of hours before the Discourse rebuild. Might that be relevant? I set up the Let’s Encrypt certificate separately for the forum subdomain than for the rest of the site. Update. My forum has just given me my one-year “Annive…

I rebuilt the app and, after removing the forum from the app and adding it again, it’s working now! …“apple_touch_icon_url”:"https://forum… Who knows whether it was by rebuilding the app again or changing the force https setting… Maybe that setting will prevent it happening again though. Thank…
